- Linguistic intelligence (language, metaphor and analogy)
- The hunters-gatherers of pre-history were experts in all these domains, but those differente kinds of expertise did not mix

- What caused cognitive fluidity?
- Self-awareness may have integrated intelligences that for thousands of years had been kept separate.
